IMPORTANT: Be careful that the protrusions on
the holder (11) catch on the notches of the slide
plates (10) (Fig. 5).
Now you must enter the time and date for the
night sky that you would like to see with your
Astro-Planetarium (observation time span). To
do this, turn the knob for setting the date (5) until
the desired date appears under the time on the
time scale (6) (Fig. 6).

INFO: The stars, planets, etc, are always diffe-
rently positioned in the sky because the Earth is
rotating. That is what it is not always possible to
see all objects. For this reason, it is important that
you always set the correct date and time before
starting a projection with your Astro-Planetarium.

Explanation of the time scale (6)
Only the time span between 8:00 pm and 2:00 am
is depicted. During this time, it is possible to see
stars in the sky no matter what the season (night
sky). Each bar on the scale corresponds to 30
minutes (Fig. 7).

With the date scale of the knob, you can set the
365 days of the year according to the month. At
30 days per month, each bar on the scale corre-
sponds to 2 days (Fig. 8). The long lines always
represent the last day of the previous month;
underneath, the respective following month is
always given.
Some examples of correct time and date set-up
Example 1:
You would like to have your Astro-Planetarium
project the night sky for July 7, 12:00 am (mid-
night). Turn the knob for the date set-up (5) until
the bar for "12:00 am" is situated above on the
time scale (6) between the two short bars be-
fore the "10" in the month of July (JUL) (Fig. 9).
